To all whom t may concern.'

Be itr known that l, JAMES R. HARnIsoN,

y a citizen of the United States, residing at Peoria, in the county of Peoria andl State of Illinois, have invented new and useful Improvements in Catch-Basins or Sewer- Inlets, of which the following is a`- specification.

This invention has reference to improvements in catch-basins or sewer-inlets.

The object of the present invention is to improve catch-basins of that type shown in the patent granted to` George A. Ensign, April 7, 1896, No. 557 ,7 86, by providing an attachment for such a basin which yis designed to prevent all gases `and foul odors from ascending or passing upwardly through the same, and yet which" is so` constructed as will permit waste water to `pass freely through said basin into a sewer pipe connected thereto.

Catch-basins of the type shown in the Ensign .patent and basins of similar construe` tion'are in use in a great many localities throughout the country, but the one serious objection to them is that, no provision is made for preventing the escape of the gases and foul odors which frequently rise from the sewer and pass out through the catchbasin, endangering the health of the residents residing in the vicinity of location of such' basins, to say nothingof the unpleasantness occasioned by the escape of such odors from these basins. With my attachment all these objections are overcome, and

at a small expense sanitary living conditions may prevail by the use of these basins.

More particularly,my invention comprises a preferably cast-ring adapted to be placed down in the neck or conical collar of the basin; a weighted plate having a pivotal connection with said ring, said plateadaptp ed to be opened by the weight of the `water entering said basin and to automatically the movement of the plate when it reaches its full open position. This arched plate is also preferably provided with an extension leading into the mouth of the catch-basin to divide trash entering the basin with the waste water.

In the drawings:-

Figure 1 is a partial vertical sectional view of a catch-basin` of the Ensign type with my attachinentapplieu thereto.

Fig. 2 is a perspective view ofmy attach ment, with the valve plate in an open position, and

Fig. 3 is a detail sectional view showing the preferred connection between the ring, valve plate and arched plate.`

Inthe drawings, like characters of rei'- erence denote corresponding parts through` out the figures. y

` The catclrbasin includes the body A formed with the opening B providing a mouth through which the waste-water enters thebasin leading to the sewer, and having a fiange or fianges C by means of which the basin is attached to its support. Depending from the body A of the basin is aconical coln lar or neck D which leadsto and to which the sewerpipe (not shown) is connected. At the opening of the mouth B of the basin isa grating E, and F is the cover for the. basin.

'Referring now to my attachment, 1 desig-` nates preferably a cast-ringhaving the sloping surface 2 leading to the opening 3 of the ring. This ring 1 is preferably of a smaller diameter `than the inner circumference of the body A of the basin to permit the easy placing of the ring in the basin and removal therefrom, and when in the basin, the ring will rest preferably on the wall of the neck or collar D of the basin below the plane ofthe flange or flanges C. Tt is also preferable when using the attachment with a type o-fbasin illustrated, to incline the pe ripheral edge of the ring, as at 4C, to provide a reasonably true fit between the ring 1 and the neck or collar D of the basin, whereby there is no opening left between these parts.

At opposite points and oli" center, said ring 1, is provided with depressed bearings 6, seeFig. 3, in which may be journaled trunnions 7 connected with a valve plate 8. The cap-plates for covering the trunnions and forming a complete bearing for the same,

are designated 9, and are preferably cast integral with legs 10 of an arched plate 11, the cap plates of the arched plate 11 being bolted or otherwise suitably secured to the rin 1. The arched plate 11 is of such a height as not to interfere with the cover F of the basin, when it is in place, and one side of the arched plate 11 is preferably eX- tended, as at 12 which projects into the mouth of the basin for the purpose of dividing any trash which may enter the basin With Waste Water. The extension of said arched plate and the plateitself serves as a protector or shield for the valve platevvhen open, and is engaged by the valve plate When- 1n open position to limit the swing of said plate. 4

The valve plate 8 has the Weighted portion 13, formed on or attached to the underside thereof, vvhich serves to normally hold the valve plate in the closed position shown in full lines in Fig. 1, and said valve plate is provided With a lng extension 5 adapted to engage With the ring l when it is swung to its closed position.

The trunnions 7 on the valve plate 8 are preferably located oi center of said plate, the Weight 13 serving to balance theplate and return it to its closed position after the operation of opening the valve, caused byl the Waste Water passing into and through the basin. The Water entering the basin and Jfalling upon the unvveighted part of the valve plate will swing the valve into the open position shown in dotted lines in said Fig. l.

It is obvious that I have provided an eX-` ceedingly practical and simple attachment of the character referred to, which may be manufactured at the lowest possible cost, and which may be applied to basins, in construction, similar t0 the one illustrated Without any change in the construction of said basin; also, that the attachment is adaptable to other a'nd similar basins.

What I claim is 1. An attachment for catch-basins of the character described, comprising a ring-like member, said member having trunnion seats, a weighted plate having oppositely located trunnions adapted to have a bearing in the trunnion seats in said ring-like member, and

an arched member, said member having cap-v plates adapted to be attached to said ringlike member and cover said trunnions.

2. An attachment for catch-basins of the character described, comprising a ring-like member, said member having trunnion seats,

character described, comprising a ring-like-V member, a valve plate having a pivotal connection with said ring-like-member and provided With a lug adapted to engage With said ring-like-member when said plate is in a closed position, and an arched member connected to the opposite sides of said ring-likemember, said` arched member adapted to serve as a stop for said Weighted plate when sWunO` into open position.

4E. n attachmentfor a catchbasin having a mouth portion and a depending neck or collar, comprising a ring -likemembei; adapted to rest Within said Vneck or collar of the basin, a valve plate having a pivotal connection with said ringflike-member, and an arched member connected to the opposite sides of said ring-like-member, said `arched member having an extension: on one sideof Which is adapted to extend into the mouth of the basin to divide any trash entering the basin With the Waste water and to form a stop for saidvalve plate when in open position.

in said ring-like-meinber, a Weight attached to said valve plate, and an arched memberr connected toopposite sides of saidring-likemember.
